headlight switch

[res0wc18]

hey all,

would a bad headlight switch cause a battery drain down? The switch is giving my the usual ford issue related to the dimmer part.

Also the light that indicates that the parking brake is on comes on and goes off several times while driving with the parking brake off?

And the last one is the steering column which is a tilt wheel is loose and moves left to right? Is there something i can tighten up? Or something that may be loose or worn out? Fix?

And last but not least the air conditioning compressor clutch is turning on and off every like 10 seconds, i unplugged it and it doesn't do it anymore?

would a bad headlight switch cause a battery drain down?

Only if it was leaving some lights on, or had a wire shorted to ground.

The switch is giving my the usual ford issue related to the dimmer part.

The dimmer-switch and headlight-switch are TWO completely independent switches.

If you have the crappy column-mounted dimmer, dis-connect that junk and get yourself one of the good ones that screws to the floor where dimmers are supposed to be.


Ford headlight wiring is about as shoddy as it gets; many trucks have burned to the ground on account of it.


There is a little TAN wire, about the size of a fiddle-string, that should be as thick as a thumb, that you will find to be all burnt and melted, just waiting to burn down your truck.


RELAY the headlights and move any trailer-lights and auxilliary markers to seperate individual switches, and your headlight-switch will last forever.

Also the light that indicates that the parking brake is on comes on and goes off several times while driving with the parking brake off?

This is an indication of slack in the park-brake cable, due either to rear shoes needing adjustment, or the cable itself needing tightening.


USE THE PARK-BRAKE every time you park, or the cables will rust and sieze internally and freeze up the brakes.

Regarding the A/C clutch - not to sound dumb - do you have the defrost on? Is everything off when it is doing it? Have you checked the switch and wiring?

I have been able to identify my "Daytime running light Module" as a culprit for an unidentified battery drain. I removed it and have to this point not had a single instance of NO battery in the morning.

Prior to removal, I had intermittent issues with a dead battery in the morning or after leaving the truck for a while.
